While there’s no one right way to sell a business, seller financing is a common approach to acquiring a business. It involves you (the owner) to finance a portion of the purchase price. Seller financing often makes your small business more attractive to buyers and increases the chances your business sells quickly.
However, it's important to understand potential tax implications when using seller financing. With seller financing, the buyer pays you directly over time, and you still own the asset until the buyer pays off the loan. We’ll break down everything you need to know about seller financing and what it could mean for your taxes.
This article is for general education, not tax advice. Tax rules depend on your deal structure, entity type, and state, so work with a CPA before you agree to terms.
What Is Seller Financing?
Seller financing, also called owner financing, is when you, the seller, lend the buyer part of the purchase price. Instead of receiving everything at closing, you receive a down payment plus a series of payments over time, documented in a promissory note. That promissory note is often called a seller note.
Typically, when using seller financing, the buyer and seller will prepare a promissory note which includes the details of the arrangement, including the payment schedule, the principal amount, and any interest charges. The buyer will often make a direct “down payment” to the seller, which is between 10% and 30% of the total purchase price.
A typical structure looks like this:
The buyer pays a portion of the price at closing, from their own cash, an SBA or bank loan, or both
You carry the rest as a seller note, usually over a few years, with interest
The note is often secured by the business's assets and a personal guarantee from the buyer
Seller financing is common in small business sales because it helps buyers bridge financing gaps. It also shows buyers and lenders that you believe in the business's future.
How Is Seller Financing Taxed?
In most cases, seller financing is taxed under the installment method (Internal Revenue Code Section 453). Instead of paying tax on your entire gain in the year of the sale, you pay tax on each portion of the gain as you receive it.
Each payment you receive has up to three parts, and each is taxed differently:
Return of your basis: Not taxed. It's your original investment coming back to you.
Gain: Taxed as you receive it, usually at long-term capital gains rates if you owned the business for more than a year.
Interest: Taxed as ordinary income in the year you receive it.
The installment method applies automatically when at least one payment comes after the tax year of the sale, unless you elect out (more on that below).
The Gross Profit Percentage
The IRS uses a simple ratio to determine how much of each principal payment is taxable gain:
Gross profit percentage = Gross profit ÷ Contract price
Your gross profit is the selling price minus your adjusted basis and selling expenses. Once you calculate the percentage in the year of sale, it stays the same for the life of the note. Each time you receive principal, you multiply it by that percentage to find the taxable gain.
A Simple Example
Say you sell your business for $1,000,000. Your adjusted basis is $200,000, so your gain is $800,000 and your gross profit percentage is 80%.
At closing, the buyer pays $200,000. You report 80% of it, or $160,000, as gain this year.
The remaining $800,000 is a seller note paid over five years: $160,000 of principal each year, plus interest.
Each year, you report $128,000 of gain (80% of $160,000), plus the interest you received as ordinary income.
Instead of reporting $800,000 of gain in one year, you report it over six tax years. That can keep more of your gain in the 15% federal capital gains bracket instead of the 20% bracket. In 2026, the 20% rate applies to taxable income above $545,500 for single filers and $613,700 for married couples filing jointly.
This example is simplified. It ignores state taxes, the 3.8% net investment income tax, depreciation recapture, and how your other income affects your brackets.
Does Seller Financing Defer Capital Gains?
Yes, partly. Seller financing defers the tax on gain until you receive the payments, so you pay as the cash comes in rather than all upfront. It doesn't eliminate the tax. By the time the note is paid off, you'll have reported the full gain.
The main benefits are:
Better cash flow matching. You aren't paying tax on money you haven't received yet.
Potentially lower rates. Spreading gain over several years can keep more of it in lower brackets and may reduce exposure to the net investment income tax.
Interest income. You earn interest on the balance, although it's taxed at ordinary income rates.
What Seller Financing Can't Defer
This is where many sellers get surprised. Several items are taxed in the year of sale, even if you've received very little cash:
Depreciation Recapture
If your sale includes equipment, vehicles, or other assets you've depreciated, the gain from past depreciation (called depreciation recapture) is taxed in full in the year of sale at ordinary income rates. The installment method doesn't apply to it. For businesses with heavily depreciated equipment, this can create a large tax bill in year one, possibly larger than your down payment.
Inventory and Receivables
Sales of inventory and accounts receivable aren't eligible for installment treatment. The portion of the price allocated to them is generally taxed when the sale happens.
How Purchase Price Allocation Affects Your Taxes
In an asset sale, you and the buyer allocate the purchase price across asset classes, such as equipment, inventory, and goodwill, and both report it to the IRS on Form 8594. The allocation determines how much of your gain is capital gain (goodwill usually is) vs. ordinary income (recapture and inventory). It's one of the most important tax negotiations in the deal, so involve your CPA early.
Benefits and Risks of Seller Financing for Sellers
The Benefits
Seller financing offers a range of benefits that make it an attractive option for both buyers and sellers.
The process is easier than going through a bank loan, allowing for faster closings.
Because there are fewer participants in the transaction, contracts tend to be simpler and less expensive than traditional bank loan agreements.
Seller financing can also help buyers who may have trouble qualifying for a loan from a bank as it allows them to be evaluated directly by the seller.
Ultimately, seller financing can offer advantages that result in smoother transactions and better deals for both the buyer and seller.
The Risks
Seller financing can help you sell your business faster and provides interest income along the way. However, there are some downsides, especially for the seller.
You take on the buyer's credit risk. If the buyer defaults, you may have to pursue collection or take back the business, possibly in worse shape than when you sold it.
If you still carry debt on the business, such as an equipment loan or line of credit, the sale may trigger payoff requirements or prepayment penalties.
Although you earn interest on the note, you receive your money over time rather than at closing, which can strain your liquidity if payments are late or missed.
If the business does not perform, you may not recoup your money.
IRS Rules on Owner Financing to Know
Charge at Least the Applicable Federal Rate
The IRS publishes minimum interest rates each month, called applicable federal rates (AFRs). If your seller note charges less than the AFR, the IRS will treat part of your principal as interest ("imputed interest"). That turns some of your capital gain into ordinary income. Set your seller financing interest rate at or above the AFR for the note's term.
The Interest Charge on Large Installment Sales
If you sell property for more than $150,000 and the face amount of installment obligations you hold from that year's sales is more than $5 million at year-end, you may owe an annual interest charge on the deferred tax (Section 453A). It's aimed at larger deals, but it's worth modeling if your note is big.
Pledging the Note Accelerates Tax
If you use your installment note as collateral for a loan, the IRS may treat the loan proceeds as a payment on the note. That triggers tax on that portion of the gain right away.
Related-Party Sales
If you sell to a related party, such as a family member, and they resell the business within two years, the IRS can treat their sale proceeds as a payment to you, which accelerates your remaining gain.
Selling or Forgiving the Note
If you later sell the note, cancel it, or forgive part of it, you'll generally have to recognize the remaining deferred gain at that point.
Electing Out
You can choose to report the entire gain in the year of sale by electing out of the installment method on a timely filed return. This sometimes makes sense, for example if you have losses to offset the gain or expect higher tax rates later. The election is generally irrevocable.
How Seller Notes Work With SBA Loans
Many buyers combine an SBA 7(a) loan with a seller note. Under current SBA rules (SOP 50 10 8, effective June 1, 2025, and carried into SOP 50 10 8.1 on October 1, 2026):
Buyers generally must inject at least 10% equity in a change-of-ownership deal.
A seller note can count toward that equity, but only for up to half of it, and only if it's on full standby for the life of the SBA loan. That means you receive no payments of principal or interest until the SBA loan is repaid.
A seller note that isn't counted as equity can be structured to pay you during the SBA loan term, as long as the lender approves and the business's cash flow supports the combined debt.
For tax purposes, a full-standby note can push your installment payments out 10 years or more, which extends your deferral. It also extends your risk. Before you agree to terms, make sure you know which kind of note you're signing and what the buyer's lender will expect from you under the SBA 7(a) loan requirements.
Installment Sale vs. Seller Financing: What's the Difference?
The terms are often used interchangeably, but they describe different things:
Seller financing describes the deal structure: you act as the lender for part of the purchase price.
An installment sale describes the tax treatment: any sale where at least one payment is received after the year of sale, reported using the installment method.
Most seller-financed business sales are installment sales for tax purposes. But an installment sale doesn't have to involve a traditional seller note. An earnout or a deferred payment schedule can also qualify.
Cost Savings of Installment Sales
The cost savings of an installment sale can be sizeable. Sellers don't have to pay capital gains taxes on the entire sale price upfront. Instead, they pay as each payment comes in, which frees up more cash in their pocket right away.
Buyers benefit from longer repayment terms and more flexible structures than a traditional loan typically offers. The interest rate is negotiated between buyer and seller, and it must be at least the IRS applicable federal rate. Buyers who have trouble qualifying for a bank loan may also have a better chance of getting approved, since the seller evaluates them directly.
Finally, both parties can often close faster, with less time spent waiting on traditional financing approval. If a bank or SBA loan covers part of the price, though, that lender's approval process still applies.
Tax Benefits of Installment Sales
There are many tax benefits associated with an installment sale. As we mentioned above, sellers pay capital gains tax on each payment as they receive it, rather than on the entire gain in the year of sale. This allows them to keep more money in their pocket now and, by spreading the gain over several years, potentially pay less in taxes overall.
Buyers can generally deduct the interest they pay on the seller note as a business expense, subject to IRS limits.
How to Report an Installment Sale: Form 6252
To report an installment sale on IRS Form 6252, Installment Sale Income, following the rules laid out in IRS Publication 537:
File it in the year of the sale to calculate your gross profit percentage and the gain on any payments received that year
File it every year you receive a payment, including the year the note is paid off
Report interest separately as ordinary interest income
Report depreciation recapture in the year of sale (it flows from Form 4797)
Final Thoughts: Plan the Structure Before You Sign
Seller financing can make your business easier to sell and your tax bill easier to manage. But the details matter: purchase price allocation, depreciation recapture, the interest rate, and whether your note sits behind an SBA loan can all change what you actually keep.

Frequently Asked Questions
How is seller financing taxed?
Most seller-financed business sales are taxed under the installment method. Each payment is split into return of basis (not taxed), gain (usually taxed at capital gains rates), and interest (taxed as ordinary income). Depreciation recapture is taxed in full in the year of sale.
Does seller financing defer capital gains?
It defers them but doesn't eliminate them. You pay tax on the gain portion of each payment as you receive it, instead of all in the year of sale.
What are the tax benefits of seller financing?
Spreading gain over several years can keep more of it in lower tax brackets, match your taxes to your cash flow, and may reduce exposure to the 3.8% net investment income tax. You also earn interest on the note.
What interest rate should I charge on a seller note?
At least the IRS applicable federal rate (AFR) for the note's term. Below-AFR rates cause the IRS to recharacterize part of your principal as interest, taxed at ordinary income rates. Beyond that, rates are negotiated based on risk and the buyer's other financing.
What form do I use to report seller financing?
IRS Form 6252, Installment Sale Income. File it in the year of sale and each year you receive a payment.
Is seller financing a good idea for the seller?
It can be, if the buyer is well qualified, the note is properly secured, and the tax structure is planned in advance. It helps close deals and can reduce taxes, but it also means taking on the risk that the buyer doesn't pay.
